Kinematics of elements of a spherical ball bearing suspension

Abstract

The kinematic constraint equations of elements of a spherical ball bearing suspension, separator and balls are considered. Based on the equation of motion of the separator and the balls, the angular coordinates of the separator and the trajectory of the centers of mass of the balls relative to the bearing surfaces are determined. Analytical expressions for determining the parameters of the separator and the balls motion are obtained for different ratios between the velocities of rotation of the rotor mounted on the outer ring and the inner ring of the suspension.
